Porto president Pinto da Costa expects Hulk to remain at the Portuguese club and says he will not leave unless a release clause is activated.
The 26-year-old scored in Brazil's 2-1 Olympic Games final defeat to Mexico on Saturday and has been strongly linked with a move to Stamford Bridge to replace the recently departed Didier Drogba.
Real Madrid, Paris Saint-Germain and Zenit St Petersburg are also thought to be interested, but now Da Costa has played down the possibility of the striker leaving, with his 78-million-pound release clause proving the stumbling block.
